"SCP-4739 isolates its victim from the outside world by enveloping them in an antimemetic field which makes it impossible for the victim, or anything done by the victim, to be perceived or remembered."

"Nobody has succeeded in physically engaging with Grey. Nobody can stall it, evade it, slow it down, reason with it or redirect it to some other target. People have tried poisoning their memories with indigestible ideas, drip-feeding their memories to Grey to slow him down, replacing their memories faster than Grey can eat them, and force-feeding Grey too many memories at once to overfeed him and blow him up."
